Dear all,
It seems I am not the only person who thinks date and tme handling is
bad in Java....see the Joda effort at
[http://joda-time.sourceforge.net/index.html](http://joda-time.sourceforge.net/index.html)
I think we should use these libraries - they claim to get rid of many of
the bugs etc of Java calndar classes; also they are directly ISO8601
based - excatly what we want in openEHR.
Rong and others - do you have any objection to using this library in the
Release 1 upgrade? I think it will reduce the coding time, and increase
the quality.

Hi all,
It does seem to be a solid API replacing Date and Calendar from jdk.
Pity that it's not an apache commons library, but people have been
mentioning a possible JSR to include Joda-time into jdk. (see
[http://weblogs.java.net/blog/mister\_\_m/archive/2006/02/tiger\_and\_dates.html](http://weblogs.java.net/blog/mister__m/archive/2006/02/tiger_and_dates.html))
I am in favor of giving it a try in the Release 1 upgrade.
